There is provided a wire electrical discharge machine that includes a temperature detection unit, an actual position correction amount calculation unit, a correction amount calculation unit, a correction amount adjustment unit, a position correction amount adjustment unit, and a corrective movement amount calculation unit. The actual position correction amount calculation unit calculates an actual position correction amount for an upper/lower guide section in accordance with reference position coordinates at a reference temperature and with actual position coordinates at a temperature different from the reference temperature. The correction amount calculation unit uses a prepared correction amount arithmetic expression. The correction amount adjustment unit calculates a correction amount adjustment value from the actual position correction amount and the position correction amount.

Wire electrical discharge machine having upper/lower guide thermal displacement correction function

A working fluid supply device of an electric discharge machine draws up a cleaned fluid from a cleaned-fluid tank by means of a pump and supplies it to a working tank. The pump is connected with a first fluid circuit configured to supply the drawn cleaned fluid to the working tank and a second fluid circuit configured to supply the drawn cleaned fluid to an ion-exchange resin and a refrigerator. In supplying the cleaned fluid to the working tank, the first and second fluid circuits are opened and closed, respectively. In supplying the cleaned fluid to the ion-exchange resin and the refrigerator, the first and second fluid circuits are closed and opened, respectively.
